embree error for displacement

V-Ray V-Ray for 3ds Max Issues
1

just tried to do a super high res render, with displacement set to 3 pixels.. i was kinda expecting it to run out of ram, but it didnt, it errored out way before then.

get error: error building embree static raycaster, error message: [embreerayserver::doBuildSDTree] 3:Setting vertex buffer failed (number triangles 743192544)

ok so it IS a lot of triangles… but, it seemed to fail immediately hence not a ram issue? does the embree static raycaster have a triangle count limit?

Hello,

It is indeed a RAM issue - when trying to allocate place for those triangles. You could probably try to turn OFF the static displacement option - then the displacement will be dynamic geometry and the necessary parts could fit. Rendering would probably be slower though..
